The optical fiber layer includes an optical cable housing used to form an optical cable perforation, an optical cable and an optical cable container arranged in the optical cable perforation. The shell converges the cladding. The optical cable housing includes multiple guide bars. Each guide bar is provided with an optical cable receiving groove on one side adjacent to other guide bars. The two optical cable receiving grooves of the adjacent two guide bars are combined. To form an optical cable perforation, the conductor layer is formed by stranding multiple strands of wires tightly attached to the optical cable housing and the bundled cladding; the optical cable includes an outer sheath, a tube skeleton, an inner sheath and multiple optical fiber bundles arranged in sequence from the outside to the inside. The inner cavity of the inner sheath is filled with thermally conductive water-blocking fiber paste, and the pipe skeleton is formed by the first steel strip spirally wrapping the inner sheath. Both the outer sheath and the inner sheath are made of heat-insulating materials.

CN116500737A discloses an optical fiber ribbon cable for communication, which has at least one optical fiber ribbon; it is characterized in that there are four assembly parts, and the assembly parts are composed of a first side cylinder, a second side cylinder, and a third side cylinder. The four assembly parts are assembled to form a closed central cavity and four side column cavities; the optical fiber ribbon is located in the central cavity. When there are multiple optical fiber ribbons, the multiple optical fiber ribbons are distributed in a stacked manner in the central cavity.

The main drawbacks of the above-mentioned prior art are: (1) After the casing is formed, it cannot be changed and can only be used in a specific structure.

A hypotenuse 111 is bent at an angle of 60 degrees, and a second right-angled side 113 is bent at a right angle relative to the first right-angled side 112 along the bending mark 100 between the first right-angled side 112 and the second right-angled side 113 and toward the first oblique angle.

Compared with the existing technology, in this application, the space is fully utilized without causing waste of space. In the case of optical cable, the first transmission part 2 and the second transmission part 3 are both light guide elements inside, which maximizes the fiber core. Density; when it is a cable, the first transmission part 2 and the second transmission part 3 are conductive elements inside, so that the number of cable cores is increased, and multiple channels of power can be transmitted at the same time, or multi-phase power can be transmitted at the same time; when it is an optical-electric hybrid cable At the same time, it not only increases the core density of the optical carrier, but also realizes simultaneous transmission of light and electricity in the same cable. Moreover, the utilization of space is maximized without waste.

In Implementation Example 3 of the present application, the cross section of the cable core is in the shape of a diamond. Correspondingly, the outer sheath 5 can also be in a corresponding shape, but slightly enlarged, so as to maximize the use of space and save materials.

In the prior art, when the layered optical cable has 12 units, 12 round loose tubes are used. When covered by the outer sheath, no matter how they are combined, they cannot minimize the space occupied. The material consumption of sheaths and other materials is the least, because the combination of circles always has unused gaps, and the combined size is too large, resulting in an increase in the consumption of materials such as outer sheaths, an increase in product size, and an increase in space occupation. The cost increases; however, this application adopts a unique solution to solve the above-mentioned problems that cannot be unified.

In the existing technology, circular loose tubes can only be formed by extrusion, etc., and cannot be changed after forming. Loose tubes of one size and specification can only be used in one series, and are used in optical cables with stranded structures. , after the diameter of the loose tube is determined, in order to form a round cable core, the size of the central reinforcement can only be changed. At the same time, in order to make the central reinforcement and the loose tube circumscribe, the adjacent loose tubes circumscribe, and all The loose tube completely covers the 360-degree circumference of the outer edge of the central reinforcement. The outer diameter of the central reinforcement and loose tube must satisfy the following relationship: D/d=1/sin(180/n)-1, where D is the center. The diameter of the reinforcement, d is the outer diameter of the loose tube, n is a positive integer not less than 3; and in this application, if the dimensions of the first transmission component 2 and the second transmission component 3 are known and they are commonly used, The split part 1 can also be prefabricated; moreover, a large-sized split body can also be manufactured first, and the split part 1 can be manufactured according to the actual size of the first transmission part 2 and the second transmission part 3, so that there will be no waste of the split parts. , and because there is no first transmission component 2 and second transmission component 3 inside, even if it is scrapped, the cost is much smaller than in the prior art; moreover, the split body can be easily recycled and reused, and there are The loose tube of optical fiber or conductor is extremely difficult to separate the material of the inspection tube body.

Mark the other end of the hypotenuse of the second transmission component 3 as the third bend mark; align one end of the hypotenuse of the second transmission component 3 with the third bend.
